It was impressive when Robert Bowling, creative strategist for Call of Duty studio Infinity Ward, paid $500 for a batch of indie games that only cost $85. Then Notch, maker of Minecraft stepped up, with $2000.

These guys and a few others are paying lots of money for the Humble Indie Bundle 2, which went on sale yesterday. The bundle is the second offering of indie games being offered to gamers for any price they want to pay. People can name their price and direct their payment in different proportions to the games' developers and various charities.
